Hi guys - bought a P115 2nd hand from a friend and it was working fine until I bought the LP-1 pedal unit for the piano. When the pedal unit is plugged in, the piano is in CONSTANT sustain mode. The issue has nothing to do with reversing polarity because pressing down on the pedal does not cancel out the sustain. The only way to stop the piano going into sustain mode is to unplug the pedal.


When this first happened, I thought the issue might be with the pedal unit, so I returned the unit and got a brand new one -- same issue. The issue has to be with the keyboard it self.

What's more, I cannot turn the keyboard off using the power key. Pressing the key any amount of times / holding it down etc no longer works. I have to unplug the piano to turn it off,

Are these glitches fixable?

That's not the correct triple pedal unit for the P115.

So, there's a chance that the pins on the connectors are not identical and the pedal unit could have caused some damage.

Fixing it probably means replacing some of the electronics and a Yamaha service center or other such business can tell you more after having a look at the piano.

Oh wow! I was convinced the 3x pedal unit had said it was compatible with the P115. Complete brain fart! I'll try with a regular sustain pedal and see if that fixes anything.

Try the FC4A sustain pedal instead. It works well on the P-115.

For a P115, the 3x pedal is the LP5A. But it should be fixed on the dedicated stand
